Application filed January 29, 1920. Serial No. 354,969.

To (all who/wit may concern: 7 Be it lmown that I, Jenn B; LINTERN, a :21 oi .the United States, residing at and, in the county or Cuyahoga and I-hio have inventeda vice rolling thereon to obtain proper traction. My sander designed to be operated m ,::l'1anicaily to release sand at the bottom of a itacle allowing the desired quantity oi." it to descend by gravity for immediate" track, thereby lnsuring' applicz ion to the good traction; notwithstanding grease, snow, or ice on the track, and thus increases efli' cieney and safety in operation, 7 i

More specific objects and features of my invention will be more fully hereinafter explaine'd, thereof are summarized in the claims.

A preferred embodiment of my sanding I device is illustrated in the drawings, where- 'in Figure 1 is a side elevation with parts of the rei-eptacle broken away; Fig. 2 is a vertical section on the line 22 of Fig. 1; Fig. 3 is a similar section at right angles showthe lower portion-of the mechanism and -!.a hen 'on the bottom plan. oi the device; and and (3 are horizontal sections on the corresponding lines oi" rigs. l and 2.

Referring to the drawings,I have shown a sand; receptacle l0 comprising a cylindrical body 11 havingan annular flange 12 at one end and a removable lid or cove'rv' l3 fitted over the other end. flange '12, as by bolts 14, is 15 having a central discharge opening or orifice l6. turned or produce a downwardly lip having relatively sharp lower edge 17, constituting a valve seat. the edge of the orifice may be beveled as prising a valve adapted to cooperate with thevalve seat 17, is provided in the form of certain new ei'ul improvement in Sanding Demed to release sand so that it may passonto the trackway to enable'a de-x and the essential characteristics Jon thethreaded end ofthe rod. The nut may belo'cked' if desired, asby a set screw 7 39. A cap or casing 68 may rest on a shoiil periphery of the plate 25 and of the rod '30.

For supporting and guiding the valve plate 20,1 have provided a rod 30 slidably received withinthe receptacle. 10; Afbearing plate is spaced from the bottom plate 15 andsuppo'rted thereby as by spacing sleeves 3 2 secured by bolts-31 passing up wardly' through the bottom 15 and sleeves and having their threaded engagement within openings in the plate 25. ing surroundedby asleeve 26 adapted to slidablyembrace the rod 30.

The rod 30Vis passed through a central opening inzthe valve plate 20 and through a hollow boss rigid with the plate 34. The upper portion of the rod; is carried within the sl eev'e 26 of the plate 25 as bearing,. and projects fora distance above theplate 25. Betweentheplate 25 andthe upperend ofxthe rod 30: is 'afspring-3t' compressed thereoii'and secured in position .by anut '38 der 6'? on the constitute with the plate 25' an 'inclosing honsim for the spring 3T'and upper portion The lowerendof th 'e r od is preferably enla;

Above the orifice 16 the rod may carry spider 66, which when the rod 30 is moved vertically.

In use the receptacle 10 is filled with sand whichsurrounds the casing-68 and fills the space between the supporting legs formed by the bolts 31 and sleeves 32'. The valve plate 20 with its sleeve 35 resting on the enlarged lower end dOof the rod 30, is held upwardly against the valve seat 1 7 under.

the tension of the spring 37,'reacting be the upper end of the. rod.

.When it is desired to. release sand onto] the track, the shaft 57 is oscillated to move the tappet arm 62 downwardly and through the engagement of the latter with the roller 43 in the bifurcated end ofithe rod 30, the latter is moved downwardly against the tensionof the spring 37, thereby separating the valve plate 20 from its seat 17 and permitting the sand to fiow by gravity downwardly. through the orifice '16, around the periphery of the valve plate 20, and through V the funnel into the conduit below. Upon release of the shaft 57, the spring 37 immediately returns the rod 30 and valve plate 20 to its former position, the sharp edge 17 of the valve seat cutting throughthe sand above the valve plate, and permitting the latter to seat immediately. with its flange 22 surrounding-the edge 17, and shut off. the

flow of sand. 7 This operation may be reieated whenever desn'ed, the-spider (5G agitating the sand and preventing its becom ing raked above the orifice 1G. I I
